PROCESS OF SEPARATING MAGNETIC FROM NON-MAGNETIC PARTICLES.

SPECIFICATION forming part of Letters Patent No. 410,876, datedSeptember 10, 1889. Application tiled March 29, 1888. Renewed January26, 1889. Y Selial No. 297,747. (No model.)

To cir/ZZ whom it may concern,.-

Beit known that I, GURDON CONKLING, a citizen of the United States,residing at Glens Falls, in the county of Warren and State of New York,have invented new and useful Improvements in the Process of SeparatingIron or other Magnetic Particles from Non-Magnetic Substances, of Whichthe following is a specification.

The principal object of my invention is to remove. from magnetic ironore the particles of iron free from phosphorus or other detrimentalimpurities in an economical manner; but my invention can be applied withadvantage to many othersubstances where it is desirable to separatemagnetic particles from non-magnetic substances.

The apparatus which can be used in carrying out my invention isillustrated in the accompanying drawings, in which- Figure 1 represen tsa vertical section in the plane a Fig. 3. Fig. 2 is a Asimilar sectionin the plane y y, Fig. 3. Fig. 3 is a plan or top view. Fig. 4 isatransverse section in the plane .e z, Fig. 1. Fig. 5 is alongitudinalvertical section of a modification.

Similar letters indicate corresponding parts.

In the drawings, the letter A designates a trough, which is supported bythe frame B and which is placed in an inclined position. (Best seen inFig. 2.) For the purpose of adj Listing the inclination of the troughthe following means may be used: To the under surface of saidtrough,near one of its ends, are firmly secured two eyes a., one near eachside, and through these eyes extend a rod b,which has its bearings inthe frame B. The opposite end of said trough is supported by tWo arms cc, Figs. 1 and 4, which are rnily secured to its under surface and whichare provided with slots c. Through these slot-s extend studs c2, theouter ends of which are provided with screw-threads to engage with nutscs, so that the trough can be turned on the rod b and secured to therequired inclination by means of the nuts c3.

Above the trough A is situated an endless belt C, which runs over twodrums D D, the shafts of which have their bearings in standards E E, andto one of which is imparted a revolving motion by suitable means, suchas a belt and pulley. In proximity to the endless belt C are placed oneor more magnets F, which maybe permanent magnets orplates magnetized byelectro-magnets. The magnets F are secured to transverses F', which aresupported by screw-studs f f, so that the magnets F can be raised orlowered. By -referring to the drawings, (particularly Fig. 1,) it willbe seen that the belt C is placed in an inclined position to correspondto the inclination of the trough A. If the inclination of the trough Ais changed, that of the belt C must also be changed to correspond, andin order to accomplish this object in the simplest possible manner Iplace the standards E E, which form the bearings for the shafts of thedrums D D, upon a frame Il, which is firmly connected to the trough A,and the screw-studs f f, which support the transverses F and magneticplates F, are also secured to this same frame, so that if theinclination of the frame A is changed the belt C and the magnets F mustfollow, and the required relation between the trough and the belt ispreserved at all times.

The substances to be separated, after having been comminuted to asuitable iineness,are mixed Withwater or other suitable liquid andconducted in a thin stream upon the trough A. When the apparatus is tobe used for separating the iron particles contained in the tailings of awet-ore separator, such as a jigger, such tailings may be conducted tothe trough A directly from the jigger through a trough I. As the streamcontaining the substances to be separated passes beneath the belt C, themagnetic particles contained therein are lifted up from and out ofcontact with said stream by the magnets F F, so that they adhere to theunder surface of the belt C, and by this belt they are carried away inthe direction of the arrow marked on said belt in Fig. 2 until theyreach the scraper J, by the action of which they are swept off from thebelt and caused to drop down into the receptacle K.

From this description it will be seen that the magnetic particlescontained in the stream of liquid running down over the trough Aarelifted'up from and out of said stream by the attraction of the magnet ormagnets F and then collected in the receptacle K, while the TOO streamcarrying the `non-magnetic particles continues on its course withoutobstruction, and the particles which have been attracted by the magnetsare not liable to be swept ott' by the stream of liquid passing downover the trough.

In the example shown in Fig. 5, the letter A designates the trough,which is supported by the frame B. C is the endless belt7 which ex- Iotends in the directionot the trough and beyond its lower end. Themagnetic particles which are attracted by the magnet Fand adhere to thebelt C are collected in the receptacle K.

\Vhat I claim as new, and desire to secure by Letters Patent, is-

The Hthin-described process for separating magnetic from non-magneticparticles, which consists in exposing a running stream ot' liquidcontaining the substances to be separated to the action of a magnet,lifting the magnetic particles carried by said stream up from and out ofcontact with the stream, and finally conducting the particles which havefollowed the attraction of the magnet into a suitable receptacle.

In testimony whereof l have hereunto set my hand and seal in thepresence ot two subscribing witnesses.
